Abstract: Many wireless sensor network (WSN) applications and techniques require sensor location to work correctly. Information fusion in WSNs is crucial for location discovery and many information fusion techniques have been used in several location-discovery algorithms. In this paper, we provide an overview of information fusion techniques used by localisation algorithms to enhance and simplify the position computation process. Furthermore, we analyse several approaches that can be used by localised information fusion algorithms and discuss how these approaches enhance the performance of information fusion and make information fusion play a leading role in localisation algorithms. This paper provides an introduction to different localised information fusion methods for node location discovery in WSNs and could be used as a starting point for implementing existing proposals or designing new techniques.
Keywords: localisation system; information fusion; localised algorithms; WSNs; wireless sensor networks; sensor's position.
